Description

Technical Field

[0001] The present invention relates to the field of remote control housing, and specifically to an injection molding device for remote control housing. Background Art

[0002] A remote control is a wireless transmitting device. Through modern digital coding technology, the key information is encoded, and light waves are emitted through an infrared diode. The light waves are received by the infrared receiver of the receiver and converted into electrical signals, which are then decoded by the processor to demodulate the corresponding instructions to achieve the required operation requirements for controlling the device. In the assembly process of existing remote controls, molds are usually used to injection-mold the housing to meet the assembly work of various components of the remote control.

[0003] After the existing remote control housing is injection-molded, the molded remote control housing is usually pushed onto the conveying mechanism by a pusher rod. Due to a certain distance between the mold body and the conveying mechanism, the molded remote control housing may deviate when falling, causing it to fall to both sides of the conveying mechanism, reducing the overall working efficiency of the device. Generally, after the existing remote control housing is molded, on the production line, workers will also perform color difference detection on the upper surface of the housing. Since the remote control housing is placed in different states on the conveying mechanism, workers need to place the upper surface of the remote control housing upward. This process reduces the overall detection efficiency and increases the workload of the workers.

[0004] In summary, the above structure may deviate during the blanking process, causing the remote control housing to fall to both sides of the conveying mechanism, and during the subsequent color difference detection process, workers need to place the upper surface of the remote control housing upward, which reduces the overall detection efficiency and increases the workload of the workers. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an injection molding device for remote control housing to solve the technical problems that the remote control housing may deviate during the blanking process and fall to both sides of the conveying mechanism, and during the subsequent color difference detection process, workers need to place the upper surface of the remote control housing upward, increasing the workload of the workers.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An injection molding device for remote control housing, including a workbench, a conveying mechanism, a color difference detection component, and a frame. The frame is located on the top of the workbench, and the color difference detection component is located on one side of the frame. A front template and a rear template are arranged inside the frame, and the rear template is slidably arranged in the frame. A support plate is arranged on the inner wall of the frame at the top of the conveying mechanism, and a mounting block is arranged on the top of the support plate.

[0007] The mounting block is provided with a special-shaped sliding groove. One side of the special-shaped sliding groove is elastically slidably provided with a push rod. A material discharging groove is provided on the support plate. A sealing plate cooperating with the push rod is rotatably arranged in the material discharging groove. The overall length of the sealing plate is less than the height between the conveying mechanism and the support plate. The bottom of the rear template is provided with a guide post cooperating with the special-shaped sliding groove. A ejector rod cooperating with the guide post is slidably arranged on the rear template, and the ejector rod is located at the upper part inside the rear template.

[0008] By adopting the above technical solution, the transmission of the gear drives the ejector rod to eject the injection-molded remote control housing, so that it falls into the material discharging groove of the support plate. Subsequently, when the rear template continues to slide, it will push the push rod to move. Under the action of the special-shaped gear, the sealing plate in the material discharging groove is slowly opened. During this process, it is ensured that the remote control housing stably falls onto the conveying mechanism. During the process of the rear template resetting for injection molding, the sealing plate rotates in reverse, so that it is arranged with the upper surface facing up on the conveying mechanism. During this process, there is no need for manual adjustment of the state of the remote control housing.

[0009] The present invention is further configured such that the color difference detection assembly includes a detection frame and a color difference meter body. One side of the frame is threadedly connected with the detection frame, and the color difference meter body is detachably arranged at the top inside the detection frame.

[0010] Preferably, when the remote control housing moves to the bottom of the detection frame through the conveying mechanism, it is detected by the color difference meter body on the inner wall, so as to directly detect the color difference during the production process to meet the industry standards or customer requirements.

[0011] The present invention is further configured such that a tooth block is provided on one side of the guide post. A fixed gear is meshed on one side of the tooth block. One end of the fixed gear is connected with a unidirectional threaded rod. The outer wall of the unidirectional threaded rod is in threaded connection with the inner wall of the ejector rod.

[0012] Preferably, during the process of the guide post moving upward under the action of the special-shaped sliding groove, the fixed gear is driven to rotate through the tooth block on one side. During this process, the fixed gear makes the unidirectional threaded rod at one end rotate, thereby driving the ejector rod to slide to one side to complete the material discharging work on the rear template.

[0013] The present invention is further configured such that one end of the push rod is connected with a tooth bar. A special-shaped gear is meshed at the top of the tooth bar. One end of the special-shaped gear is connected with the sealing plate.

[0014] Preferably, when the guide post drives the push rod to move, the special-shaped gear is driven to rotate under the action of the tooth bar, thereby driving the sealing plate in the material discharging groove to flip by a certain angle.

[0015] The present invention is further configured such that the special-shaped gear is connected to one end of the transmission mechanism, and a bidirectional threaded rod is connected to the other end of the transmission mechanism. Positioning plates that cooperate with the bidirectional threaded rod are slidably arranged on both sides of the conveying mechanism at the top of the workbench.

[0016] Preferably, when the sealing plate flips downward, the positioning plates slide on both sides under the action of the transmission mechanism and the bidirectional threaded rod, so as to ensure that the formed remote control housing can stably fall onto the conveying mechanism. When the sealing plate flips back to its original position later, the positioning plates will move inward, thereby adjusting the position of the remote control housing, making the remote control housing in the middle position on the conveying mechanism, which is convenient for the subsequent color difference meter body to perform color difference detection on it, and further improving the overall detection accuracy.

[0017] The present invention is further configured such that threaded sleeves are symmetrically and slidably arranged on the outer wall of the bidirectional threaded rod, and a connecting rod is connected between the top of the threaded sleeve and the positioning plate.

[0018] Preferably, during the rotation of the bidirectional threaded rod, the threaded sleeves on its outer wall will be driven to slide. During this process, the threaded sleeves will drive the positioning plates at the top to slide accordingly. Thus, during the rotation of the bidirectional threaded rod, the positioning plates themselves will slide and adjust accordingly.

[0019] The present invention is further configured such that the transmission mechanism includes a driving disk, a transmission belt, and a driven disk. The driving disk and the driven disk are connected by the transmission belt. One end of the driving disk is connected to the special-shaped gear, and one end of the driven disk is connected to the bidirectional threaded rod. Among them, the diameter of the driving disk in the transmission mechanism is larger than that of its driven disk.

[0020] Preferably, during the rotation of the special-shaped gear through the toothed rod, the driving disk will be driven to rotate. Under the action of the transmission belt, the driven disk drives the bidirectional threaded rod to rotate. Thus, the subsequent adjustment work of the positioning plates is realized. Since the diameter of the driving disk in the transmission mechanism is larger than that of its driven disk, when the special-shaped gear drives the sealing plate to flip by a certain angle, the driven disk will drive the bidirectional threaded rod to rotate several circles, so as to ensure the adjustment of the positioning plates on the workbench.

[0021] The present invention is further configured such that a groove is provided at the top of the workbench at the position of the threaded sleeve, and the inner wall of the groove is in contact with the outer wall of the threaded sleeve.

[0022] Preferably, under the action of the groove, when the threaded sleeve slides inside, it can effectively prevent the threaded sleeve from rotating by itself following the bidirectional threaded rod, and further improve the sliding stability of the threaded sleeve.

[0023] The present invention is further configured such that a cylinder is provided at the top of the detection frame, and the output end of the cylinder is connected to the rear template, wherein the cylinder is used to drive the rear template to slide reciprocally.

[0024] Preferably, under the action of the cylinder, it is convenient for the staff to control the mold opening and closing operation between the rear template and the front template to ensure the overall production efficiency.

[0025] The present invention is further configured such that a chute is provided at the top of the workbench, and the frame at the rear template is slidably arranged itself.

[0026] Preferably, under the action of the chute, it is convenient for the frame to drive the detection frame and the rear template as a whole to slide. When the staff needs to replace the mold, the frame can be slid to one side. During this process, the replacement efficiency of the mold body can be increased, and at the same time, it is convenient for subsequent maintenance and cleaning of the gap between the support plate and the sealing plate, effectively preventing the waste from obstructing the rotation of the sealing plate.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. In the present invention, a support plate is provided on the inner wall of the frame. When the rear template slides open to one side after the injection molding is completed, the guide post at the bottom of the rear template will contact the special-shaped chute. During the sliding process, the guide post moves upward under the action of the special-shaped chute. During this process, through the transmission of the gear, the ejector rod is driven to eject the injection-molded remote control housing, making it fall into the blanking groove of the support plate. Subsequently, when the rear template continues to slide, it will push the push rod to move. Under the action of the special-shaped gear, the sealing plate in the blanking groove slowly opens, realizing that the remote control housing in the blanking groove slowly slides downward and falls onto the conveying mechanism. During this process, it is ensured that the remote control housing stably falls onto the conveying mechanism, and during the blanking process, the corners of the remote control housing are effectively prevented from being knocked.

[0029] 2. In the present invention, a color difference detection component is provided on one side of the frame. The overall length of the sealing plate is less than the height between the sealing plate and the conveying mechanism. When the sealing plate is in an inclined state through the special-shaped gear, one end of the formed remote control housing will contact the conveying mechanism, and the inner surface of the remote control housing is upward. Subsequently, during the process of the rear template resetting for injection molding, the sealing plate rotates in reverse. At this time, the remote control housing is flipped under the action of the sealing plate, making it have its upper surface upward on the conveying mechanism. During this process, there is no need for manual adjustment of the state of the remote control housing, saving a large amount of manpower and material resources and accelerating the overall detection efficiency.

[0030] 3. In the present invention, positioning plates are slidably arranged on both sides of the sealing plate on the workbench. When the sealing plate is turned downward, the positioning plates slide on both sides under the action of the transmission mechanism and the bidirectional threaded rod, so as to ensure that the formed remote control housing can stably fall onto the conveying mechanism. When the sealing plate is turned over and reset later, the positioning plates will move inward, thereby adjusting the position of the remote control housing, making the remote control housing in the middle position on the conveying mechanism, facilitating the subsequent color difference detector body to perform color difference detection on it, and further improving the overall detection accuracy.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation of the present invention.

[0045] The embodiments of the present invention will be described below according to its overall structure.

[0046] The first embodiment:

[0047] Please refer to Figures 1-11 An injection molding device for a remote control housing as shown, which includes a workbench 1, a conveyor mechanism 2, a transmission component, a detection component, a blanking mechanism and a flipping mechanism. Among them, a frame 4 is located on the top of the workbench 1. A front template 11 and a rear template 9 are arranged in the frame 4, and the rear template 9 is slidably arranged in the frame 4 through a cylinder 8. The cylinder 8 is used to push the rear template 9 to slide to one side and close the mold with the front template 11. Then, glue is injected into the mold through the glue injection nozzle on the front template 11. After cooling is completed, the cylinder 8 is used to drive the rear template 9 to open the mold. A support plate 5 is arranged on the inner wall of the frame 4 at the top of the conveyor mechanism 2, and a mounting block 10 is arranged on the top of the support plate 5. An irregular chute 22 is provided on the mounting block 10, and a guide post 23 is elastically arranged on the rear template 9. When the cylinder 8 drives the rear template 9 to move to the mounting block 10;

[0048] It slides into the special-shaped chute 22 through the guide post 23. Since the shape of the special-shaped chute 22 is a steep slope shape from low to high, and the guide post 23 itself can slide in the vertical direction, when the guide post 23 contacts the special-shaped chute 22, due to the shape factor of the special-shaped chute 22, the guide post 23 will slide upward. During the sliding process, it is pushed to one side by the ejector rod 21 on the rear template 9 to complete the blanking work on the rear template 9. Since the ejector rod 21 is located at the upper part inside the rear template 9, the remote control housing will fall onto the sealing plate 7 in the blanking chute 12 with its inner surface upward. At this time, the sealing plate 7 is horizontally arranged in the blanking chute 12. When the air cylinder 8 continues to drive the rear template 9 to slide to one side, a push rod 18 is elastically arranged in the special-shaped chute 22, and the guide post 23 will push the push rod 18 in the special-shaped chute 22 to move to one side. Since one end of the push rod 18 is connected to a rack 16, a special-shaped gear 17 is engaged at the top of the rack 16, and one end of the special-shaped gear 17 is connected to the sealing plate 7;

[0049] When the guide post 23 drives the push rod 18 to move, the special-shaped gear 17 is driven to rotate under the action of the rack 16, so as to drive the sealing plate 7 in the blanking chute 12 to turn by a certain angle. Thus, under the action of the special-shaped gear 17, the sealing plate 7 in the blanking chute 12 is slowly opened, realizing the slow downward sliding of the remote control housing in the blanking chute 12 and falling onto the conveying mechanism 2. During this process, it is ensured that the remote control housing stably falls onto the conveying mechanism 2, and the corners of the remote control housing are effectively prevented from being knocked during the blanking process. Subsequently, after the blanking is completed, the air cylinder 8 will push the rear template 9 to perform the mold closing work towards the front template 11 on one side;

[0050] Since the overall length of the sealing plate 7 is less than the height between the conveying mechanism 2 and the support plate 5, during this process, when the sealing plate 7 is in an inclined state through the special-shaped gear 17, one end of the molded remote control housing will contact the conveying mechanism 2, and the inner surface of the remote control housing is upward. Subsequently, during the reset injection molding process of the rear template 9, the push rod 18 is reset under the action of the elastic component, thereby realizing the reverse rotation of the sealing plate 7. At this time, the remote control housing is turned under the action of the sealing plate 7 to be in an upward state on its upper surface on the conveying mechanism 2. During this process, in cooperation with the color difference detection component on one side of the frame 4, there is no need for manual adjustment of the state of the remote control housing, saving a large amount of manpower and material resources and accelerating the overall detection efficiency. The elastic component in this application can be understood as a mechanism that can push the push rod 18 to reset, and it can specifically be a spring, a spring sheet or other products or mechanisms with elastic potential energy.

[0051] In the above embodiment, specifically, please refer to again Figure 3, where the color difference detection component includes a detection frame 3 and a color difference meter body 13. The detection frame 3 is threadedly connected to one side of the frame 4, and the color difference meter body 13 is detachably arranged at the top inside the detection frame 3. When the remote control housing is moved to the bottom of the detection frame 3 through the conveying mechanism 2, it is detected by the color difference meter body 13 on the inner wall, so as to directly detect its color difference during the production process to meet industry standards or customer requirements.

[0052] In the above embodiment, specifically, please refer to Figure 9 , where a tooth block 24 is arranged on one side of the guide post 23, a fixed gear 25 is meshed on one side of the tooth block 24, and one end of the fixed gear 25 is connected to a one-way threaded rod 26. The outer wall of the one-way threaded rod 26 is in threaded connection with the inner wall of the ejector rod 21. During the process of the guide post 23 moving upward under the action of the special-shaped chute 22, the tooth block 24 on one side will drive the fixed gear 25 to rotate. During this process, the fixed gear 25 makes the one-way threaded rod 26 at one end rotate, thereby driving the ejector rod 21 to slide to one side to complete the blanking work on the rear template 9. The ejector rod 21 and the one-way threaded rod 26 are actually the relationship between a threaded rod and a threaded sleeve. The limiting mechanism between them belongs to the prior art for those skilled in the art, and there is a limiting mechanism inside the mold, so it is not elaborated in detail.

[0053] The second embodiment:

[0054] Please refer to Figure 1 、 Figure 4 and Figure 5 A remote control housing injection molding device shown in the figure. The overall structure is similar to that of the first embodiment. Among them, the special-shaped gear 17 is connected to one end of the transmission mechanism 15, and the other end of the transmission mechanism 15 is connected to a bidirectional threaded rod 14. On the top of the workbench 1, positioning plates 19 that cooperate with the bidirectional threaded rod 14 are slidably arranged on both sides of the conveying mechanism 2. When the sealing plate 7 is turned downward, the positioning plates 19 will slide to both sides under the action of the transmission mechanism 15 and the bidirectional threaded rod 14, so as to ensure that the formed remote control housing can stably fall onto the conveying mechanism 2. When the sealing plate 7 is turned over and reset later, the positioning plates 19 will move inward, thereby adjusting the position of the remote control housing so that the remote control housing is in the middle position on the conveying mechanism 2, which is convenient for the subsequent color difference meter body 13 to detect its color difference, further improving the overall detection accuracy.

[0055] Please refer to Figure 1 and Figure 5, symmetrically sliding sleeves 20 are arranged on the outer wall of the bidirectional threaded rod 14. The top of the threaded sleeve 20 is connected to the positioning plate 19 through a connecting rod. During the rotation of the bidirectional threaded rod 14, the threaded sleeve 20 on the outer wall will be driven to slide. During this process, the threaded sleeve 20 will drive the positioning plate 19 at the top to slide accordingly. Thus, during the rotation of the bidirectional threaded rod 14, the positioning plate 19 itself will slide and adjust accordingly. And a groove 6 is provided at the position of the threaded sleeve 20 on the top of the workbench 1. The inner wall of the groove 6 is in contact with the outer wall of the threaded sleeve 20. Under the action of the groove 6, when the threaded sleeve 20 slides inside, it can effectively prevent the threaded sleeve 20 from rotating on its own along with the bidirectional threaded rod 14, further improving the sliding stability of the threaded sleeve 20.

[0056] Please refer to Figure 4 , wherein the transmission mechanism 15 includes a driving pulley, a transmission belt and a driven pulley. One end of the driving pulley is connected with a special-shaped gear 17, and one end of the driven pulley is connected with the bidirectional threaded rod 14. During the rotation of the special-shaped gear 17 through the rack 16, the driving pulley will be driven to rotate. Under the action of the transmission belt, the driven pulley drives the bidirectional threaded rod 14 to rotate. Thus, the subsequent adjustment work of the positioning plate 19 is realized. Since the diameter of the driving pulley in the transmission mechanism 15 is larger than that of its driven pulley, when the special-shaped gear 17 drives the sealing plate 7 to turn by a certain angle, the driven pulley will drive the bidirectional threaded rod 14 to rotate several circles to ensure the adjustment work of the positioning plate 19 on the workbench 1.

[0057] The third embodiment:

[0058] Please refer to Figure 3 An injection molding device for a remote control housing as shown. On the basis of the second embodiment, a sliding groove is provided on the top of the workbench 1, and the frame 4 at the rear template 9 is slidably arranged itself. By sliding the frame 4, the detection frame 3 and the rear template 9 as a whole are driven to slide. When the staff needs to replace the mold, by sliding the frame 4, the replacement of the mold body is realized, and at the same time, it is convenient to maintain and clean the gap between the support plate 5 and the sealing plate 7 later, effectively preventing the waste from obstructing the rotation of the sealing plate 7.

[0059] When the present invention is in specific operation: During use, the rear template 9 is pushed by the cylinder 8 to slide to one side and is clamped with the front template 11. Subsequently, glue is injected into the mold through the glue injection nozzle on the front template 11. After cooling is completed, the rear template 9 is driven by the cylinder 8 to open the mold. When the guide post 23 at the bottom of the rear template 9 moves to the mounting block 10, the special-shaped sliding groove 22 on the mounting block 10 causes the guide post 23 to move upward. During this process, the ejector rod 21 is pushed to one side to eject the formed remote control housing through the cooperation of the tooth block 24 and the fixed gear 25. Since the ejector rod 21 is located at the upper part inside the rear template 9, the remote control housing will fall onto the sealing plate 7 in the blanking chute 12 with its inner surface facing upward. As the rear template 9 continues to slide open the mold, the guide post 23 drives the push rod 18 to move. During this process, the sealing plate 7 is driven to rotate at a certain angle through the action of the toothed rod 16;

[0060] The sealing plate 7 is inclined in the blanking chute 12, so that the remote control housing on the sealing plate 7 slides downward slowly and falls onto the conveying mechanism 2. During this process, it is ensured that the remote control housing falls stably onto the conveying mechanism 2, and the corners of the remote control housing are effectively prevented from being knocked during the blanking process. After the blanking is completed, the cylinder 8 pushes the rear template 9 to move and clamp the mold. During this process, the push rod 18 is reset through the action of the elastic component. When the guide post 23 slides out of the special-shaped sliding groove 22, the elastic component also follows to reset. During the process of the sealing plate 7 resetting and flipping, the remote control housing is flipped under the action of the sealing plate 7 so that it is set with its upper surface facing upward on the conveying mechanism 2. During this process, there is no need for manual adjustment of the state of the remote control housing, saving a large amount of manpower and material resources and accelerating the overall detection efficiency.

[0061] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and are not limitations to the invention. The described specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
